Replaced KDE (older, KDE4, in fact) specific icon and
launcher (.desktop file) installation & uninstallaton
invocations in Makefile with those that use Freedesktop.org
`xdg-...` tools.
Manpage still showed that "--fullscreen" (with no value) could be
specified. Lately, it requires =yes, =no, or =native.

Also, remove a duplicated credit from the contributor list.
Ability to disable stereo panning effect (e.g., paint brush, UI
elements sound effect feedback, etc.), useful for users with
hearing impairment in one ear, or situations where one speaker or
headphone is being used. Use "--nostereo" command-line option
or "nostereo=yes" config. file option.
The thumbnails for starters & templates are NOT being re-generated
when the source images are modified -- only when the thumbnail is
missing. Needs an update to the target's prerequisites
(but I'm very rusty with this level of Makefile magic).
Also, update some Starter source images so they work better with
flood fill (Bald Eagle, World map, Gecko).
"Fill", as a new main-toolbar tool, was not recording snapshots
of the image for the "Undo" tool. Mended.
However, also updated the tool so that it doesn't _bother_ recording
into the undo buffer if the fill action is a no-op (e.g., clicking
the same spot a second time, or otherwise attempting to fill an
area with a color that's identical to what's already on the canvas).
Also generating and installing thumbnails of Template images,
thus getting "New" dialog to open extremely quickly.
(Pretty much "instantaneously" on my 8 year old laptop with
Intel i3 @ ~2GHz and Intel 320-series SSD (214 MB/s).)
Providing better command-line args to ImageMagick `convert` to
produce nice-looking thumbnail PNGs of Starter images.
(N.B. - I'm using "ImageMagick" Version: 8:6.9.7.4+dfsg-16ubuntu6.7)
I cannot recall[*] why we disabled the steps to generate thumbnails of
starters (".thumbs/STARTERNAME-t.png") and install them in the system
directory (e.g., /usr/local/share/tuxpaint/starters/.thumbs/),
but every time one goes to create a new image ("New"), it took a very
long time to show.
[*] If anyone remembers ~a decade ago, and has a good reason, let me know!
Also, remove "Makefile" as a prerequisite for some targets; if anything
major changes in there, it's expected one will run "make clean" or
remove the binary/etc. target and rebuild. (Rebuilding "tuxpaint.o"
every time I edited something unrelated in Makefile was really annoying :) )
Replace the somewhat-recently-added "nothing" item in the tool bar
with the "Fill" tool, which has been converted back from a Magic tool
to a regular tool.
Also, change bash "==" to sh "=" in "if [ ... ]" tests in Makefile.
Also, link to math library (via "-lm") to make sure "max()" is available to
magic tools.
Also, add missing mention of "--newcolorslast" and "--newcolorsfirst" to manpage.
